查询词典 fragment

MRI FFE can improve the diagnostic ratio of the extrusion of nucleus pulpous,annular bulge as well as free disc fragment.

MRI快速场回波序列可提高椎间盘突出症的椎间盘纤维环断裂、髓核脱出方向以及神经根受压诊断的准确率。

Resilts In the observation of cervical nucleus pulpous prolapse and free disc fragment showing fibrous circle rupture,extrusion direction and nerve-root pressure in cervical region,and showing fibrous cicrcle rupture in lumbar region,the FFE was better than T1WI,T2WI.In judging extrusion direction and nerve-root pressure,the FFE sequence was better than T2WI and T1WI respectively.

结果在颈椎间盘髓核脱出与游离的观察中FFE序列对纤维环断裂、髓核脱出方向以及神经根受压的发现率均明显优于T1WI、T2WI；在腰椎间盘髓核脱出与游离的观察中FFE对纤维环断裂的显示率明显优于T1WI、T2WI；对髓核脱出方向的判定明显优于T2WI；对神经根受压情况的判定FFE优于T1WI。

Primary culture of goat mammary gland cells could be derived by outgrowth of migrating cells from fragment of tissue. Fibroblast and epithelial cells could be pured according to their different sensibility to trypsin. Complex cultures treated by 0.25% trypsin in Hanks' for 5~7min at 37℃, the dispersed cells were mainly fibroblasts,then the rest treated by 0.15% trypsin-0.02% EDTA in Hanks'for 5~8min at 37℃, the majority cells harvested were mammary epithelial cells.

用组织块培养法可获得良好的山羊乳腺细胞原代培养物；培养的山羊乳腺成纤维细胞比上皮细胞对胰蛋白酶更敏感，据此可在传代过程中将二者分离纯化，获得纯细胞系；混合培养物先用0.25%胰蛋白酶在37℃消化5~7min 所收集的细胞主要为成纤维细胞；再加0.15%胰蛋白酶-0.02鞹A 消化液在37℃继续消化5~6min 所回收的细胞绝大多数为上皮细胞，经过2~3 代，即可得到纯化的乳腺上皮细胞系。

It can be concluded that the cloned sequence is putatively hsp70a cDNA fragment from Dunaliella salina.

所克隆的序列为盐藻hsp70a cDNA 片段。

Substituent effect of pyrazoles was also investigated by DNMR and DFT.We successfully synthesized these intermediates with exclusively-conformations in a mild condition. X-ray results show that substituents in the pyrazolyl ring affect greatly on the structures of products, especially theπdelocation of the fragment 1-metal-butadiene.

本文以取代吡唑和1-炔基Fischer卡宾化合物的Michael加成反应合成了12个-型β-吡唑基烯基卡宾化合物，反应条件温和。X-ray晶体衍射显示吡唑上取代基对产物结构，特别是1-M-丁二烯的共轭程度具有较大的影响。
